BrazilWhat I'm looking for
I am a Senior Backend Engineer focused on designing and maintaining scalable, high-performance APIs and distributed systems. I bring strong experience with Amazon Web Services and building reliable backend solutions for fintech, e-commerce, and enterprise environments.
Over the years, I’ve led backend teams, implemented maintainable architectures like Hexagonal Architecture and DDD, and driven improvements in performance and scalability. I’ve optimized database queries to reduce response times on critical endpoints and integrated messaging with RabbitMQ for robust distributed workflows.
I’m hands-on with backend development across PHP and Java ecosystems, including Node.js, Laravel, and Java Spring microservices. I also contribute through technical workshops and engineering practices such as SOLID, Clean Code, and TDD with BDD—ensuring systems stay maintainable as they grow.
